24.5.2 Setting the maximum number of multipaths handled by the Switch

The maximum number of multipaths used for each protocol in the Switch determines the maximum number of multipaths that the Switch handles and the maximum number of multipath routes that the Switch can handle.

The maximum number of multipaths is determined at startup, and any changes made by configuration commands do not take effect until the switch is restarted. If you use a configuration command in a manner that affects the maximum number of multipaths, a warning-level operation message appears prompting you to restart the switch. The new values for the maximum number of multipaths and multipath routes will take effect after the Switch restarts.

Points to note

The default maximum number of multipaths handled by the switch is 16. For multipath routes, AX3800S series switches handle a maximum of 256 and AX3650S series switches handle a maximum of 128. To change the maximum number of multipaths that the switch handles, you must restart the Switch after setting the maximum number of multipaths in the configuration of a unicast routing protocol. For this reason, we recommend that you set the maximum number of multipaths when you first deploy the switch.

The configuration below uses an example of IPv6 static routing.

Command examples

1. (config)# ipv6 route static maximum-paths 2

   In configuration mode, sets 2 as the maximum number of multipaths for IPv6 static routes.

2. (config)# ipv6 route 2001:db8:ffff:2::/64 2001:db8:2:1::2 noresolve

   (config)# ipv6 route 2001:db8:ffff:2::/64 2001:db8:2:2::2 noresolve

   In configuration mode, establish a static IPv6 multipath route (2001:db8:ffff:2::/64).

3. (config)# save

   (config)# exit

   Saves the settings and switches from configuration mode to administrator mode.

4. # reload

   Restarts the Switch.
